WILLIAM MBLEY, oF RoUNnGRovE, ILLINOIS LAWlw-grrowrzrt1A'r'rACEMENTl yApplication filed October 31, 1931. Serial No. 572,414.

r-Ihis invention relatesk broadly to lawn mowers and the primary objectof the invention is to provide means yfor retaining the-r fixed cuttingblade kof the lawn mower from jumping up and down as the lawn mower 1s moved over the turf thus insuring the cutting of the grass in an evenV manner, the present 4 objection being, that `the cutting blade beingl permitted this up and down movement, re-

l@ sults in a ragged or irregular cutting of the ofrass. D Briefly, the invention consists in the provision of an elastic connection between vthe. handle of the lawn mower and the bumper bar l5 for `that bar of the lawn mower which eX- tends between and connects the gear housing usually provided on the wheels of the lawn mower, together with means for regulating tension of the elasticconneotion. e

Other objects and advantages of the invention will become apparentfrom a study of the following description, taken v`in connection with the accompanying drawings wherein:

Figure l is a plan view of a portion of a lawn mower-having my inventiony applied thereto. f

Figure 2 is a sectionalview taken substanj tially on the line 25-2 of Figure l.V

Figure 3 is a perspective view of a clamp. vReferring more in detail to the drawings,

it will be seen that I have shown the invention as applied to a conventional type of lawn mower, the only part of which to be here` inafter more specifically referred to, being r such parts of the lawn mower as the present invention'is concerned. `Such parts lare the Abumper bar 5, that extends between the gear casings of the lawn mower adjacent the front of the mower, the handlek 6, andthe fixed cutting blade 7. r

In carrying out my invention, and in the preferred form thereof, there isprovided a clamp 8 that is preferably madeof strap `iron and adjacent one end provided with a return Q'adapted to straddle the bumper bar 5.

Opposed portions of theY bar ,forming the gaged therewith a nut r 11. Obviously,

'12 there is connected: one end of a length of' bend to provide a substantially U-shaped partk through the medium `of thenut and bolt;v means,-the opposed portions of the U may be contractedk about the bar 5to secure the clamp 8 in position thereon against casual displacement, and' with the end of the clamp l y8 extending upwardly.

The uppermost endl of the clamp is apertured for accommodating one end of a coil spring l2. To the freeend of the coil spring, 60 chain lvthat is adapted to have a selected one of it's'links engaged with a hooklt suitably mounted on the handle `6 adjacent the lower end thereof. Obviously, by placinga` desired link ofpfthefchain 13 engaged with the hook l14, the desiredtension on spring l2 may be obtained.

From the foregoing, it. will be seen that I have provided adjustable elastic means for connecting the handle 6 of the lawn mower with the bumper bar 5 of the lawn mower and this connection serves to retain the 'blade 7 parallel to the ground, preventing the up and down movement of the blade 7 to which movement the blade is often subjected, during cutting.

kEven though I have herein shown and described the preferred embodiment of the in-y vention, it is lto be understood that the same is susceptible of' further'changes, modiica- 80 tions and improvements coming within the f scope of they appendedk claim.

I-Iaving thus describedmy invention, what I claim` as new is: v

An attachment for a lawn mower including a handle, a rotary cutter reel and a bumper bar located in front )of the reel and slightly below the horizontal planeof the top part of the reel, comprising a U-shaped bracket having one limb longer than its other, and said bracket fitting over the bar with its limbs eX- tending upwardly therefrom, a bolt passing f throughan,intermediate portion of the long limb and through the upper end yof the short limbfor clamping the bracket to the bar,y a spring connected tov the upper end of the long limb, a` hook on the handle, anda chain g connectingthe spring with said hook.

In testimony .whereofI afiixmy signature.
